Filed July s,l 1919 2 sheets-sheet 2 24e i l lulu Application. filed To @ZZ whom t may concer/1t Be it known that Meeren H. BLANK and ARTHUR H. Enenefron, citizens oit the United States, residing at Cleveland, in lthe county or" Cuyahoga and lntate et Ohio, have invented certain new and use ul improvements in Wheels, oit which the following is a speciication, reference being had therein to the eccex 'rnyirwf drawings.

This inver n rV Les to wheels for road vehicles and our improvements are especially useful as applied to wheels `for motor trucks or other vehicles designed to carry heavy loads.

@ne object or the invention is to produce a metal wheel in which great strength and light weight are combined.

Another object of the invention is to devise a metal wheel in which the material is termed and disposed in such manner that the wheel can readily he cast trom metals having; the characteristics of aluminum alloys.

A. further object or" the invention is to devise huh and hearingl construction es pecially suited tor use with metals cast ot aluminum alloys or other metal that is relatively soft in comparison with iron.

Another ohject ot the invention is to provide a metal wheel with an improved telly and rim construction in which said telly and rim are east in one with the web or hody oi the wheel.

Other objects more or less ancillary to the foregoing, and the manner in which the various objects are' attained, will he pointed out in the following description.

ing a modiiied torni of huh and hearing construction.

let'erring .first to the wheels shown in 1 and 2, 1 is awheel huh which is forined at its inner and outer ends to receive antitriction hearings 2 and 3, respectively, of well known construction. The hearings 2 a nd 3 receive a lined axle Ll upon which the wheel is securedv hy a nut 5. rlhe nut 5 alouts the end ot the inner race of hearing 3 and a shoulder la on the arde 4i similarly ahuts the inner race oi' the hearing 2. ln addition, the wheel huh 1 is Jformed interiorly with annular flanges 6 and 7 which abut the inner ends of the outer races of the bearings 2 and 3, respectively. Thusprovision is made for axial thrust in both directions. The outer end of the huh is threaded to receive a cap 8. 9 is a packing ring' consisting,- preferably of a heavy washer oil telt or theY like hetween two thin metal washers, the latter being pressed `upon the axle 4.

rllhe hub 1 is rformed with inside and` outside sections 1a, ll.b which converge outwardly and join the inner edge" ofa vweh 10. ylhe huh structure strengthened by a circumferential series of ribs 1c. fit its outer edge this weh shows what, by analogy, may he termed the wheel telly 11. This telly comprises inner and outer sections 11a, 11b which diverge ontw rdly to torni a wide hase for the wheel rim. rlhe wheel hub 1, the web and thejfelly 11 are cast in one.

The wheel rim may he cast in one with the -telly or may he formed separately. ln the wheel shown in ligs. 1 and 2 the rim 12 is in one with the telly 11, the structure thus termed being suhstantially triangular in radial section. ...fit its inner side the rim 12 rhas integral tire )flange 12a and at its outer side said rim is formed with a groove 12b to receive the locking ring 13 for the removable tire flange 14. The Wheel is thus adapted to receive a large pneumatic tire 15 of the cord type. rlhe telly of the wheel is cut away at 16 and the wheel rim 12 is formed with a slot 17 to accommodate the tire valve 18. rlhe wheel rim 12 may be formed with a circumferential series of core openings 19.

A wheel of the character described can he driven in any suitable manner hut, in the construction shown, the telly of the wheel is formed with a circumferential series of bolt holes 0 to perinit the attachment of o driving sprocket or geur.

We pret rnbly cust our improved Wheel of en sluniininn alloy suitable for the purpose9 und We thus secure s Wheel which is reinztrl sbly light. fit tl e sfnie tiine, ample strength is secured by the nie-.nner or" forining the hub und iel erts or the Wheel, At Will loe noted in this connection that the load applied through the bearings il und 3 is very effectively susnined by the inner und outer converging hub sections la end lb und directly transmitted through seid sections to the web l0. and also that the loud or stress is in n, Qiiriler insnner eiiectively and directly trans ited troni the web l0 through the diverW 'folly sections lla und 1lb to the riin l2.

Furthermore. it oi construction to possible with our 'torni innle the thickness of the cost sections very uniform so that ditlicul ties, which would otherwise be encountered in the costing` of ehnninuni alloys, nre obviated.

The hub cup 8 iney, ci course, be formed oii nluininuin und rl :fe lat ond the the tiro nu j locking` ring' 13 rnny be torined either orp uluniinuin elloy or other inctel.

lin 3 is shown n wl' l designed for use the front Wheel oi n truelr. ln this cese the hub Q1, 'web and telly 23 are cust in one. but the Wheel is provided with o sepnrnte steel riin Qlvvhich designed to be applied to the Jtelly with u forced lit. The inner und outer sections of the hub ure strengthened, us in the ense oi' the first 'torni of construction, by internal ribs 21a, and es the inner und outer sections or" the telly 23 nre not in this cese tied together by the riin. the telly is provided Witn circumferentinl series of t" The transverse ribs 23a. folly hss its outside section cut nvey st Q31 ond is nt this point provided with n.` peripheral well 23 receive the tire vulve ss shown.

The hub o'tthc wheel is provided at its inner end will n steel sleeve 25 Which forms n sont for the inner bearing. fnd, sirnilsrly, the outer end of the Wheel hub is orn'ied with s steel sleeve 26 to forni n sent for the outer bearing. The sleeve 26 is preferably orn'ied with en internal flange 26a to telic the if-:inl thrust in one direction end insegne tion. lille have shown the Wheel hub in this este `provided with steel sleeves to serve as sents for the bearings as it muy be found desirnblc in soins cases to protect the relstively soit nlnininuin alloy freni the shocks in entreine ceses, result. By the use of the steel sleeves the stresses incident to severe shocks incre evenly di tributed.

designed 'for flee o1; :i heavy :el ornied with bolt holes 33 richer-ent of driving sprocket or geni' ond thc folly 34 is Yenined with diverginginner and outer sections es in the above described forzns of construction. ln the present esse, however, the telly, because or" its greet Width, is formed `with :t circu.L erentinlly extending,` rib Slt-C Which springs 'from the outer section Slb ot the telly. This rib is tied to the inner section by rirn section ond e series of transverse ribs u :tnsverse ribs 3'?.

.s shown, the Wheel is provided vvith a of solid tires 38 which consist of steel bese rings 38 upon which the rubber trends 38h are vulcanized in the Well known Inanncr. The tires are placed upon the Wheel with s forced lit, the inner tire losse ring engaging the riin section 35, While the outer tire bese ring engages both the riin section 35 endthe outer periphery oiz the telly section 341.

As in the cese of the tivo other forms of construction above described7 the loads or stresses are effectively end directly susteined and transmitted by the Wheel structure by virtue oi the outwardly converging Wells or sections orp the hub and the outwerdly diverging sections of the telly.

ln 5 end 6 We show en alternative forni ot construction for the inner end of the Wheel hub. ln this construction the huh All is provided its inner end with en annuler flange d2 to tolte the axial thrust in one direction of the outer race of e bell benri 123. The inner race ci this bearing is mounted with e. forced lit on en axle LA and at its inner side shuts e shoulder on the erle ns shown.

The outer race of the bearing preferably lits the hub il rather snugly but in eddition it is positively secured in position in the hub by nieens or". e securing` ring 45. This ring is threaded on its outer periphery to lit :i threaded herd metal sleeve i6 which is preferably secured to the hub by casting iaeaiaa the hub ot aluminum alloy on the ring. rlhe sleeve t6 can he termed with projections as shown which are deeply embedded in the metal ot the huh and serve to anchor the sleeve very securely. With this construction the screw threads ot both members are termed in hard metal and ample strength is attained without making the threads unduly heavy. The inner periphery ot the retaining ring flo is tormed with a groove to receive a' packing 417 ot telt or the like.

With this torni ot huh and bearing construction it will he seen that axial thrust in both directions is transmitted to and trom the hub through the inside bearing ot the wheel. Consequently the outer end ot the hub need not he provided with tlanges or the like to taire thrust, but the outer race ot the outside bearing may simply be mounted in the hub with a snug tit.

`We wish it understood that we do not limit our invention to the specific torms ot construction which have been shown and described, except as indicated in the claims which tollow.

W hat we claim is:

l. A cast metalwheel having a hub with outwardly converging inside and outside sections, an annular web joining the converging),` huh sections at their junction, a tellj7 with inside and outside disc sections diverging outwardly trom their junction with the outer edge ot the web, said hub, web and telly parts beingl cast in one, and a metal rim surrounding the telly and engaging directly with the said diverging sections, the rim and telly forming a hollow structure substantially triangular in radial section.
